为了方便理解本发明的上述技术方案，以下通过具体使用方式上对本发明的上述技术方案进行详细说明。In order to facilitate the understanding of the above-mentioned technical solution of the present invention, the above-mentioned technical solution of the present invention will be described in detail below through a specific usage mode.
在具体使用时，本发明将笔记本、耳机和转接器连接作为测听设备，并将声级计与耳机相连进行校准。笔记本计算机上声卡的不同输出值对应产生的不同声强、不同频率的声音，声级计是一种声音测量仪器。在进行校准时，声级计通过专业耳机接收来自笔记本计算机上声卡的声音信号，通过调整声卡输出，产生符合要求的声音信号，此时记录声卡输出。重复以上步骤，完成所有频率、声强测试点输出的记录。测量结束后，对数据进行线性拟合，完成声强-声卡输出坐标图的绘制，然后选取部分点进行验证，如果验证误差过大，提示校准失败，需要重新校准，如果验证误差在容许范围，则提示校准成功。将校准数据存储，以备测听之用。In specific use, the invention connects the notebook, the earphone and the adapter as audiometry equipment, and connects the sound level meter with the earphone for calibration. The different output values of the sound card on the notebook computer correspond to the sounds of different sound intensities and frequencies. The sound level meter is a sound measuring instrument. During calibration, the sound level meter receives the sound signal from the sound card on the notebook computer through professional headphones, adjusts the output of the sound card to produce a sound signal that meets the requirements, and records the sound card output at this time. Repeat the above steps to complete the output recording of all frequency and sound intensity test points. After the measurement is over, perform linear fitting on the data, complete the drawing of the sound intensity-sound card output coordinate map, and then select some points for verification. If the verification error is too large, it will prompt that the calibration failed and needs to be re-calibrated. If the verification error is within the allowable range, It will prompt that the calibration is successful. Store calibration data for audiometry purposes.
如图1所示，首先选择校准方式，如果选择自动校准，则具体的校准方法包含如下步骤：As shown in Figure 1, first select the calibration method. If automatic calibration is selected, the specific calibration method includes the following steps:
步骤201）调整计算机声卡输出，获得特定频率和特定声强的标准声音；Step 201) Adjust the computer sound card output to obtain a standard sound with a specific frequency and specific sound intensity;
步骤202）确定标准声音是否达到指定的精度，如果没有达到标准精度则返回步骤201；否则，记录特定频率和特定声强的标准声音与输出的对应关系；Step 202) Determine whether the standard sound reaches the specified accuracy, if not, return to step 201; otherwise, record the corresponding relationship between the standard sound of a specific frequency and specific sound intensity and the output;
然后判断是否完成所有标准声音的测试，如果完成则进入步骤203）；否则返回步骤201）直至完成所有标准声音的校准测试；Then judge whether the test of all standard sounds is completed, and if it is completed, enter step 203); otherwise, return to step 201) until the calibration test of all standard sounds is completed;
步骤203）将记录的特定频率和特定声强的标准声音与输出的对应关系进行先行拟合，得到拟合曲线；Step 203) Fitting the corresponding relationship between the recorded standard sound of a specific frequency and specific sound intensity and the output to obtain a fitting curve;
步骤204）验证拟合曲线是否在容许的误差范围内，如果在则校准完成；否则返回步骤201），直至拟合曲线的误差在容许范围内；Step 204) Verify whether the fitting curve is within the allowable error range, if so, the calibration is completed; otherwise, return to step 201), until the error of the fitting curve is within the allowable range;
步骤205）记录最终的特定频率和特定声强的标准声音与输出的对应关系，完成校准。Step 205) Record the final corresponding relationship between the standard sound of a specific frequency and specific sound intensity and the output, and complete the calibration.
此外，由于电脑传出的声音信号是由声卡输出控制的，声卡输出与声音信号的声强、频率是一一对应的关系。根据这个原理，在进行听力测试时，我们利用软件控制声卡输出，发出特定频率、特定声强的标准信号，通过一个专业耳机，传入检查者耳内，以实现气导测听。同时，还能提供了一个与检查者交流的人机交互界面，使用简单。待检查结束后，还能自动绘制检查者的听力曲线，生成检查报告单，将检查数据存入数据库，实现与医院其他系统的无缝式融合。In addition, since the sound signal from the computer is controlled by the sound card output, there is a one-to-one correspondence between the sound card output and the sound intensity and frequency of the sound signal. According to this principle, when conducting a hearing test, we use software to control the output of the sound card to send out a standard signal of a specific frequency and specific sound intensity, which is passed into the examiner's ear through a professional earphone to achieve air conduction audiometry. At the same time, it can also provide a human-computer interaction interface for communicating with the inspector, which is easy to use. After the examination is over, it can also automatically draw the examiner's hearing curve, generate an examination report, and store the examination data in the database to achieve seamless integration with other systems in the hospital.
如图2所示是本发明提供的听力测试方法的流程图，具体包含如下步骤：As shown in Figure 2 is the flowchart of the hearing test method provided by the present invention, specifically comprises the following steps:
采用图1的校准方法校准测听设备，所述测听设备包含：计算机声卡、转接器和耳机；校准后选择测听功能，然后获得检测者信息，启动测听检测，具体包含如下步骤：Using the calibration method in Figure 1 to calibrate the audiometry equipment, the audiometry equipment includes: a computer sound card, an adapter and earphones; after calibration, select the audiometry function, then obtain the information of the examiner, and start the audiometry detection, specifically including the following steps:
步骤101）用于控制计算机声卡发出指定频率和声强的声音信号；Step 101) is used to control the sound card of the computer to emit a sound signal of a specified frequency and sound intensity;
步骤102）计算机声卡发出的指定频率和声强的声音信号经双声道耳机传入耳内进行听力测试，并记录听力测试结果；Step 102) The sound signal of the specified frequency and sound intensity emitted by the computer sound card is transmitted into the ear through the binaural earphone for hearing test, and the hearing test result is recorded;
返回步骤101），直到完成所有特定频率和特定声强的声音信号的测量；return to step 101), until the measurement of all sound signals of specific frequency and specific sound intensity is completed;
步骤103）依据听力测试结果绘制听力测试图。Step 103) Draw a hearing test chart according to the hearing test results.
综上所述，借助于本发明的上述技术方案，通过利用计算机声卡和专业耳机来实现听力测试，具有造价低，便于携带，使用简单，功能强大等优点，可以满足医学检查需要，并有利于患者完成听力自我监测，对于一些三线城市医院和乡镇医院极具推广力。针对声卡+专业耳机便携式测听设备，也能够便捷地完成校准工作，声音误差在合理的容许范围之内。In summary, with the help of the above technical solution of the present invention, the hearing test is realized by using the computer sound card and professional earphones, which has the advantages of low cost, easy to carry, simple to use, powerful functions, etc., can meet the needs of medical examinations, and is beneficial to Patients complete hearing self-monitoring, which is very popular for some third-tier urban hospitals and township hospitals.
